James Wilson
Chartered Accountant & Financial Planner

James established Proactive Tax and Business Services in 1998 and set about building a strong focused team. Originally from Adelaide, James and wife Catriona were drawn to the amazing lifestyle offered by the region including skiing, water sports and bush walking. As their children move further into adulthood, they plan to combine the enjoyment of travel with a work/life focus which will see them being part of the business for many years to come. As Managing Director of Proactive, over the past 22 years James has helped the business grow to the team of 12 that it is today. James completed his Bachelor of Economics from the Adelaide University and qualified as a Chartered Accountant with KPMG in 1987. He sees education as a way of life rather than a final destination, and over the years has completed training in Business Development skills and more recently has added a Diploma of Financial Planning to his repertoire. James and Catriona and their two very active children Liam (a dancer) and Hayley (a skateboarder) love to travel, enjoy the outdoors and are involved in many local community projects including Youth activities, the Arts and operation of the Mansfield Armchair Cinema – a not-for-profit community social enterprise which offers School Based Apprenticeships to local Secondary College students. Being involved in the hospitality industry for 30 years, the cinema industry for 12 years and on the board of the Adelaide Arcade, James is able to frame his professional advice for clients with real and practical experience in business which goes well beyond running a busy accounting firm.
